Histochemical Identification

Dogs from two locations in West Slovakiasuspected to have dirofilariosis were tested with the help of microfilariae detection, histochemical identification of microfilaria species and Dirofilaria immitis specific antigen detection in the blood serum. Six out of the group of 15 dogs from Bratislava region were found positive with Dirofilaria repens microfilariae. In the second location situated farther to the south, near Komarno, 6 out of 7 dogs were found positive with D. repens microfilariae and 2 with D. immitis. Serological detection of D. immitis antigen was positive in 3 cases among the dogs from this region, 2 of which were found positive with D. immitis microfilariae simultaneously with D. repens. The infection was asymptomatic in all of the dogs included in the trial.

Wide circulation of the causative agent of dirofilariasis in the natural environment and the lack of appropriate measures to identify and deworm infected animals – obligate definitive hosts (domestic dogs and cats) promotes infestation by the human helminth infections. The aim of the study is to analyze the incidence of dirofilariasis in people according to official statistics. The analysis of 52 surveillance maps collected for 2019, 2020 and official statistics on the incidence of parasitic diseases for 2019 was carried out. The analysis of the surveillance maps showed that dirofilariasis is most often registered in the south of Russia (the share of the Southern and Volga Federal Districts accounts for more than 50% of registered patients), the main group of patients with dirofilariasis falls on 30–39 year old people and older 60 years old or more (23.1%, respectively). The structure of patients with dirofilariasis is dominated by women (65.2%). Infestation is more often registered in urban residents (75%). Almost half of the removed dirofilaria, were localized in the head area (weight share of 44.2%). Among the removed helminths, females predominated (80.8%), of which 72.7% were immature. Cases of human infestation with dirofilariasis are registered throughout the Russian Federation, with the exception of the northern regions. Despite the increase in the proportion of Dirofilaria immitis, especially in the south of Russia, the disease caused by Dirofilaria repens and extremely rarely D. immitis are registered in people on the territory of the Russian Federation. It is possible that in this case there is a hypodiagnostic invasion of D. immitis.

Dirofilariasis is caused by two types of para-sitic worms – Dirofilaria immitis and D. re-pens. Both species of dirofilariaare obligate absolute parasites and are in antagonistic relations with their own hosts. The invasion caused by the adult stages of D. immitis, especially at high intensity, results in the death of 70-80% of dogs. Dirofilariasis is practically not studied in the territory of Ar-menia. The article is devoted to determining the spread of dirofilariasis and the preva-lence rates in the Republic of Armenia in the areas: Shirak, Aragatston, Armavir, Ararat and Syunik. It was found that in 100% of cases the pathogen was D. immitis. Using an immunochromatographic instrument-free test system, the average prevalence rate in the regions was revealed, which amounted to 8.5%. In 87.5% of cases, dirofilariasis was observed in the farms of Armavir and Ararat regions, which are the most disadvantaged for this disease and are recorded in dogs aged 3 to 8 years. Thus, in the territory of Armenia, a local focus of carnivorous diro-filariasis is actively functioning, which ex-tends along the left bank and on the plains along the middle reaches of the Arax riv-er from falling into it Akhuryan river and stretches from the north-west to the south-east up to Azerbaijan Nakhichevan.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.

Insight Into

The canine heartworm is a common and serious nematode parasite of domestic dogs in many parts of the world. Although nematode neuroanatomy is fairly well documented, the emphasis has been on sensory anatomy and primarily in free-living soil species and ascarids. Lee and Miller reported on the muscular anatomy in the heartworm, but provided little insight into the peripheral nervous system or myoneural relationships. The classical fine-structural description of nematode muscle innervation is Rosenbluth's earlier work in Ascaris. Since the pharmacological effects of some nematacides currently being developed are neuromuscular in nature, a better understanding of heartworm myoneural anatomy, particularly in reference to the synaptic region is warranted.
